Why quaid put the needs_love tag on the page

If a PreUpgrade stand alone page is needed, that can be created separately with feature content, then have this page linked. However, most features use their Features/PreUpgrade-style page as the main reference point, so there is no reason to create a PreUpgrade page.

Another method to free space: Convert /boot to ext2

If /boot is an ext3 filesystem it's possible to free about 4 MB by converting it to an ext2 filesystem. It goes something like this:

umount /boot
tune2fs -O ^has_journal /dev/sda1 - where /dev/sda1 is the /boot partition
$EDITOR /etc/fstab - change ext3 to ext2 for /boot
mount /boot

-- Abo

Troubleshooting - "characters: ordinal not in range(128)"

I would suggested to add one more item into troubleshooting section. When using multibyte environment with local language, PreUpgrade can end with the message like this:

Traceback (most recent call last):
  File "/usr/share/preupgrade/preupgrade-cli.py", line 329, in <module>
    pu.main(release)
  File "/usr/share/preupgrade/preupgrade-cli.py", line 267, in main
    if not self.userconfirm():
  File "/usr/share/yum-cli/output.py", line 687, in userconfirm
    choice = raw_input(_('Is this ok [y/N]: '))
UnicodeEncodeError: 'ascii' codec can't encode characters in position 4-5: ordinal not in range(128)

Solution is to prepend LANG=C to the preupgrade-cli:

LANG=C;preupgrade-cli "Fedora 15 (Lovelock)"

This bug is still present in the actual repo version of yum (3.2.28-6.fc14) or PreUpgrade (1.1.9-1.fc14). Regarding ticket is 635432.


I just tried using preupgrade as described here, and discovered a couple of errors.

  • First: After downloading the install files, the upgrade did not install upon reboot. Using the instructions, I booted into the grub command line. The grub "kernel" and "initrd" commands show the paths "/boot/upgrade/...". That's wrong, the paths should just be "/upgrade/...".
  • Next: The Advice "Upgrade to current release directly" did not work for me. Current release is 15, my installation is 12. The upgrade died with the message: "Your current installation cannot be upgraded. This is likely due to it being too old. Only the previous two release [sic] may be upgraded. To upgrade older releases you must first upgrade through all intermediate releases".

Skipping intermediate versions

The current comment implies one can update from any fedora release. When I tried to update from f12 to f15, I got the following message in a dialog box...

"Your current installation cannot be upgraded. This is likely due to it being too old. Only the previous two release may be upgraded. To upgrade older releases you must first upgrade through all intermediate releases."

... and the choice to 'Exit Installer' or 'Continue'.

I suspect this is because fedora 12 is no longer supported.

The conditions under which one can update from an older release (or not) could be spelled out more clearly. I don't know what those are for certain, so I'll leave it to someone else to add that information.

What happens if I don't click preupgrade's Reboot button on the final panel?

If I con't click the Reboot button in preupgrade:

  • I hope and reasonably expect that the system will still reboot normally in the present system version.
  • I fear that if I quit from preupgrade before clicking the button, the next time the system reboots, it will proceed to upgrade.
